flats

Pinch flats are the worst kind of flats because you get two holes in your tube instead of just one. Some people refer to them as snake bites because that’s what it looks like. This is not the typical type of flat you get on the road because it’s caused by hitting something hard enough that the tube gets pinched between the ground and rim. It is something you need to be concerned about during cyclocross season though. Cross tires are low volume and many courses have rocky sections where it will happen easily and take you out of the race.
